login managment

[Enea]

Hi to everybody,

I would like to know if someone has already faced the following problem: I
have to manage the access to a reserved area in such way to prevent that two
accounts are contemporarily active.
The problem doesn't apparently seem difficult: I add a field "loggato" in
the table "consumers" (what it also serves me for the user authentication)
and when I make the login (correct username and password) set to 1 that
field, while during the logout set to 0 that field. During the login
obviously I verify that the field "loggato" both to 0 because in contrary
case I prevent the access (the consumer is already login).

Excuse me for the premise but it was essential to understand to fund the
true problem: for the nature of the reserved area obviously I manage the
sessions with a cookie, now with the new feature that has been me in demand
it occurs the following problem: if the consumer allows to expire the cookie
or if closes the browser any reset the field "loggato" to 0 and so that
consumer cannot login anymore!

If someone is already found with a similar problem I would be really
thankful if you/he/she could give me a right-hand...

Thanks in advance.
Regards.
Enea

You may want to try sessions instead of cookies to manage logins.

I'm not clear on why setting "loggato" to zero by closing the browser is
causing a problem, though.
